It's a "second generation" tan CG DM. The original CGs had recycled Busse basic series handles, and were all sterile black, .285-inches thick. Yours is the version that has been sold at knife shows having a Busse presence since the Fall 2008 Knob Creek show (where they sold for $89.95). They were show special priced at $69.95 for the 2009 Blade Show, and have remained there since. I don't know if Dan is still churning them out for military orders, and diverts a few overruns to the shows, or if they are still selling from old 2009 Blade stock -- I guess it doesn't matter, but the DM is the only knife I know of that remained show special priced after the show was over. It's certainly a lot of knife for the money.
Where would I find them being sold were I interested in picking one up Jim?
